On classification of simple non-unital amenable C*-algebras, II

Abstract: We present a classification theorem for amenable simple stably projectionless C*-algebras with generalized tracial rank one whose $K_0$ vanish on traces which satisfy the Universal Coefficient Theorem. One of them is denoted by ${\cal Z}_0$ which has a unique tracial state and $K_0({\cal Z}_0)=\mathbb{Z}$ and $K_1({\cal Z}_0)={0}.$ Let $A$ and $B$ be two separable simple $C^*$-algebras satisfying the UCT and have finite nuclear dimension. We show that $A\otimes {\cal Z}_0\cong B\otimes {\cal Z}_0$ if and only if ${\rm Ell}(B\otimes {\cal Z}_0)={\rm Ell}(B\otimes {\cal Z}_0).$ A class of simple separable $C^*$-algebras which are approximately sub-homogeneous whose spectra having bounded dimension is shown to exhaust all possible Elliott invariant for $C^*$-algebras of the form $A\otimes {\cal Z}_0,$ where $A$ is any finite separable simple amenable $C^*$-algebras. Suppose that $A$ and $B$ are two finite separable simple $C^*$-algebras with finite nuclear dimension satisfying the UCT such that traces vanishe on $K_0(A)$ and $K_0(B)$ (but arbitrary $K_1$). One consequence of the main results in this situation is that $A\cong B$ if and only if $A$ and $B$ have the isomorphic Elliott invariant.
